Description

Parity-violating experiments like P2 at Mainz Energy-Recovering Superconducting Accelerator (MESA) demand an accuracy of polarization measurement of Δ P/P < 1%. To ensure beam polarization, a polarimetry chain with polarimeters at different energies and working principles is planned to track the electron beam polarization throughout the MESA lattice. As a part of the chain, a Mott polarimeter will be installed after the pre-acceleration of the polarized beam to 5 MeV energy. Based on extensive background simulations, the design of vacuum system and target assembly has reached its final stage. A preliminary approach towards a detection system will also be presented.
